Understanding mechanics of creping in tissue production

Creping is a part of tissue paper production process in which a very thin layer of paper is adhered on a hot, big(6-8 m dia) rotating(~2000 m/min surface speed) metal cylinder and scraped off later using a sharp blade. This process permanently changes the mechanical properties of the paper layer making it very soft, stretchy, water absorbent, which are desirable in a tissue paper.
As simple as this process may sound, this is one of the most important, but not well understood and complex phenomenon of tissue production. In short, the process is the following one :
1. Characterize tissue paper quality by measuring some parameters. ( Involves high speed imaging and simple image processing techniques)
2. Observe mechanism of creping to understand and explain it in terms of mechanics. ( Involving again high speed imaging, elementary scientific imaging) TO BE CONT’D
